Sir Anthony Bamford – the owner of Staffordshire digger giant JCB – has seen his fortune almost double in the last year, according to new research.

Sir Anthony and Lady Bamford saw their combined fortune rise by 91 per cent up to £3.150 billion according to the Sunday Times Rich List.

This comes after the Birmingham Post reported that JCB had posted record revenues in the last financial year.

However, the rise was not enough to make Sir Anthony the richest person in the West Midlands, as Kirsty Bertarelli and her husband Ernesto are worth £7.4 billion.

Staffordshire-born Ms Bertarelli, crowned Miss UK in 1988, have made their millions mainly in pharmaceuticals but Ernesto, 46, is also a leading sailor and 40-year-old Kirtsy is a professional singer and charity worker.

The Bamfords, owners of Staffordshire based plant manufacturer JCB, benefitted from a number of lucrative contracts signed with major Indian firms in the past 12 months.

Their main home is Daylesford, a 1,500-acre Gloucestershire estate, yet they also own 4,200 acres of Staffordshire land, a £20 million beachside mansion in Barbados, a chateau in Provence and a retreat in Chelsea.

Three other Midland money-makers sit inside the top 100 in the Times’ list of the 1,000 wealthiest people in the UK.

Mobile phone mogul John Caudwell, from Stoke-on-Trent, has seen his £1.5 billion value freeze but he is still the third most affluent resident in the West Midlands.

Peter Coates and his daughter Denise were able to offset their £3.5 million loss in Stoke City, the football club he chairs, against huge profits from their online gambling company Bet365.

The couple saw their fortune rise £50 million to £800 million leaving them joint 92nd on the list.

Ranked at joint 97th was Tony Murray and family whose Wolverhampton-based heating and air conditioning business helped them add £80 million to their finances leaving them £770 million in the black.
